http://www.open-mpi.org/community/lists/devel/2014/04/14496.php Revamp the opal database framework, including renaming it to "dstore" to reflect that it isn't a "database". Move the "db" framework to ORTE for now, soon to move to ORCM This commit was SVN r31557.

/* The security framework is a single-select one - i.e.,
|
|
* only one plugin is active at any time, though multiple
|
|
* plugins may build. When init is called, each plugin that
|
|
* built should check to see if it can connect to its
|
|
* respective server - if it can, then it should return
|
|
* success to indicate it is ready to be used.
|
|
*
|
|
* For scalability, it is important that each process only
|
|
* contact the security server once, and only when requested
|
|
* to do so. Thus, the plugin should not get credentials for
|
|
* the process until the first call to "get_my_credentials",
|
|
* and should then cache the results for future use.
